Description
This item is brand-new, factory sealed.
Connect wired headphones or earphones to a USB Type-C-enabled device and enjoy high-fidelity audio output with this USB-C to 3.5mm audio adapter. The built-in 32-bit DAC supports stereo sound and microphone functionality via the TRRS jack for clear and immersive audio.
Superior Sound Quality
Experience excellent sound quality supporting audio ranges from 44.1 to 384kHz and 16, 24, and 32-bit sample rates, delivering a 105dBA signal-to-noise ratio for crisp and detailed output. The stereo ADC features a 94dB SNR for microphone input, with 48kHz and 16-bit sampling, all powered by the Realtek ALC4030U chipset.

It supports wired headphones and headsets (including models with in-line controls), making it an ideal solution for using existing audio gear and eliminating the need for Bluetooth audio solutions.
Sleek and Portable Design
The compact, sleek adapter measures just 5 inches (127mm) and features a flexible and durable TPE jacket with a soft-touch finish. Use this adapter cable on the go or at a workstation for audio playback, recording, or calls.
